wrrz, a citizenof the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented al certain new and useful improvement in Locks, of which the following is 'a full, clear, and exact description, reference being had to the accompanying drawings.

The object of this invention is to provide a Very simple and efficient latch 0r lock for holding snugly together two members and preventing their relative movement.

One of the uses of my lock is for window saslies, the lock being adapted to be carried'by the meeting rails and operatingy to draw them together and securely hold them. Such an embodiment of my lock requires but three pieces (in addition to the holding screws) namely; the keeper, adapted to be, secured to Aone sashlrail; a wedge faced bolt, adapted tocoperate with. the keeper, and a third member secured to the other sashrail and adapted to retain the bolt while allowing it to be tipped over from idle to active posit-ion and to be shifted while in the active position to tighten the engagement. A

The drawings clearly illustrate my invention as applied to a sash lock.

Figure l is a vertical section through the meeting rails of the sash, showing the ,lock in engagement; Fig. 2 is similar View', showing the lock in idle position; Fig. 3 is-a plan of the lock engaged; Fig. 4 is va rear elevation of the lock engaged; Fig. is a front elevation of the lock engaged;

Fig. G is a perspective of the keeper; Fig. 7 is a perspective of the bolt; and Fig. S a perspective of the clip retaining the bolt. As shown in the drawings, A represents the bottom rail of the top. sash and B the top rail of the bottom sash. (l indicates 'the keeper attached to the rail A. 'D indicates the bolt, and E the retaining member attached to the rail B' and holding thc bolt. The keeper and retaining member are secured by suitable screws F and G, respectively, or inl any other manner, as desired.

The keeper C, as shown, comprises a base plate o and a standard e1 rising centrally therefrom and having a forwardly projecting jaw o?, the under surface of which is inclined, not oniyupwardly toward the;

portions, namely; the bail, or loop portion,

d, the operating' web or handle all, and the wedge-portion di. The upper -face of the 'wedge-portion is inclined toward the base of the member l) in the same directions as the incline of the face of the Jaw c2. The rear edge of the wedge is also preferably inclined toward the handle all. The wedge d2 is shorter than the bail by a distance corresponding to the' thickness of the ortion of the clip which retains the. bai. Accordingly, when the bolt is in oneof its extreme positions the wedge may be beyond the keeper and adaptedto be turned over past it into position to be slidbeneath the Iauw. l f

The retaining member or clip -for the bolt is indicated by ll and consists of a base plate c adapted to be secured to the rail B, and a loop in the form of an arched member c1, which rises from the plate e and then depends from that plate to a plane substantially alining with the bottom surface of the plate e. Accordingly, when the retaining member E is in place on the sash, the lower surface of the arched member e substantially abuts the top ofthe rail B. This arched member straddles the bail (Z, thereby retaining the bolt on the sash B, but allowing it, not only to be turned toward and from the other sash, but shifted longitudinally of the sash rails to' cause a tight engagement.

lt will be seen'at a glance that, in installing the parts, the keeper C is secured to the rail of the upper sash adjacent. to the front edge thereof and the lipaltl is lsecured 'to the upper rail of the lower sash at the rear edge thereof opposite the keeper and with the arch straddling the bail of the bolt.

`Fig 2 shows the idle position of the parts, thebolt being carried by the retaining mem-j ber F and 'the sashes operating independ ently of each other. To lock the sashes, it is only necessary to turn the bolt over until vits base restson the plate e, the wedge-portion d2 passing alongside of the jaw c2 .into alinement, with the space beneath it, and then to move the bolt lengthwise so that its wedge-portion comes ipto gripping contact with the-inelined under face of the jaw e?,

iii/WinA be seen that, while my lock is' very simple in construction, it is peculiarly effective, in practice, holding the parts together with great snugiiess. Moreover, my

I claim is lock is not only adaptable for usual hand operation, but may be very conveniently einployedA in inaccessible places, as, for example, large windows where it is desired. to operate the lock by means of a pole, rather than in 'the ordinary manner. Insuchhan installation, an ordinary Window pole may turn the bolt over from the position shown in Fig. 2 to that shown in Fig. l and a blow from said pole on the end of the bolt will complete the locking.

Having thus described my invention, what l. In a lock, the combination of a keeper having aninclined jaw, a bolt having a wedge coperating with the jaw, and a retaining member for the vbolt holding it to allowl it to be turned into and out of juxtaposition with the jaw and shifted longitudinally in engagement with the jaw.

2. In a lock, the combination, with a keeper, of a bolt having a bail, retaining means loosely engaging the bail whereby the bolt is held in a manner to enable it to be turned and` also shifted, the bolt andA gageable surfaces.

3. In a lock, the combination with asuitable retaining member, of, a bolt having abail loosely held by the retaining member, a handle portion and a wedge-portion, and a keeper having an inclined jaw coperating with the wedge-portion.

4. In a lock, the combinatiomwvith a retaining member having a base plate and a loop, of a bolt having a bail slidable through said loop and Yhaving a wedge-member, and a keeper having a jaw cooperating with the wedgemember.

5. In a lock, the combination, with a retaining member having a base plate and an arch, of a bolt having' a bail slidablethroiigh said arch and having a lockinglportion, a

ykeeper Vhaving a jaw cooperating with the locking portion, the bail having a part of its length opposite said locking portion, and a part which is beyond saidlocking portion, whereby the locking portion may be moved past the keeper-jaw and then slid longitudinally in engagement therewith.

6. The combination, with a suitable'lgreeper and a suitable retaining member, of a bolt having a bail coperating with the retaining member, and a Wedge eo erating withV the keeper, the bail extending eyond the-end of the wedge.

7. In a lock, thecoinbination, with akee r having a'jaw which is inclined on its un er surface in two directions, a bolt having a correspondingly 'inclined wedge-portion, and a retaining member for the bolt allowing-it to be turned and shifted longitudinally.

8. In a lock,the combination of a keeper having a base plate, a standard rising therefrom, a jaw projecting forwardly from the standard and having an under face which is inclined upwardly from the base toward the standard and also inclined in the direction of the length of the base, a longitudinally` ing a' bail, a wedge-portion and an intermediate handle portion, the wedge-portion` extending diagonally upward from the lower plane of the bail portion and terminating short of the length of the handle portion, a retaining device for the bolt and a keeper adapted to coperate with said wedge-portion.

10. In a lock, the combination, with a keeper, a bolt coperating therewith having` a bail; and a retaining member to hold the bolt comprising a base plate and an arched portion rising therefrom and depending some distance from the base, whereby when the retaining memberis removed, the bolt ,is free but when in place the bolt is held loosely.

In testimony whereof, I hereunto atlix my signature in the presence of two witnesses.-
